Note the extra connector on the card in addition to the standard PCI-e x1 connector which matches the dedicated slot on the Microserver motherboard. This presented a bit of a problem as I was using the space for the battery backup module for the RAID controller in the neighbouring slot.

Thankfully the long ribbon cable meant I could route the battery up to the space behind the DVD burner freeing the slot again. Once the card was installed and everything screwed back together I booted straight back into CentOS. Given IPMI is touted as a feature I figured that was the first thing to try so I installed OpenIPMI:

From reading the PDF manual it states that the IPMI KCS interface is at 0xCA2 in memory, not 0xCA8 that the kernel is trying to probe. Looking at the output from dmidecode shows where this value is probably coming from:

Success! With that sorted, you can now use ipmitool to further configure the management card, although not all of the settings are accessible such as IPv6 network settings so you have to use the BIOS or web interface for some of it.

Overall, I’m fairly happy with the management card. It has decent IPv6 support and the Java KVM client works okay on OS X should I ever need it but I couldn’t coax the separate virtual media client to work, I guess only Windows is supported.
